Testing fidelity to a new psychological intervention for family members of substance misusers during implementation in Italy

Providing treatment and help to family members of people with alcohol and drug problems is a new approach. In the UK, a new intervention-the '5-Step Method'- has been developed, which has shown positive results in reducing family members' symptoms and improving their coping. This method has been utilized in Italy, also with positive results. This paper analyses 52 treatment reports compiled by the treating professionals, to examine how well the method has been introduced into the Italian sociocultural context. Information about the intervention from these treatment reports was grouped into categories by independent judges. These categories were analysed using univariate statistics, followed by multivariate dynamic analysis using STATIS, a multidimensional statistical methodology capable of analysing the temporal phenomenon (over the five sessions) in question. This methodology examined the resulting 3-way matrix: cases, variables, and time. The analysis shows that the training was effective: the trained personnel did deliver the five steps and did do in each step what was suggested in the manual. It also suggests that some overall strategies, such as giving family members a plan and proposing up to five sessions with the family member are very helpful interventions. Suggestions for improving both the intervention, and for incorporating instruction in this method as part of initial professional training, are made.
